Autonomous agents

Definition

Autonomous agents are systems or robots capable of performing tasks or making decisions independently, without human intervention. They utilize algorithms and sensors to perceive their environment, allowing them to act based on their own goals and objectives. These agents can adapt and learn from experiences, which is vital in fields like evolutionary robotics, where the goal is often to evolve solutions to complex problems.
